MUTILLA ERNESTI, Sp. nov. 



Long. 5 mm. 



Hab. Trincomali, Ceylon ( Yerbury). 



Belongs to the group of M. serratula Cam., except that 

 the head is not black, only dark ferruginous. From 

 M. veda and M. indecora, it may be known by the darker 

 colour of the head and thorax, by the deeper tint of the 

 abdominal marks, and by the second abdominal segment 

 being distinctly longitudinally striolated. 



Head as wide as the thorax ; the sides behind the 

 eyes straight, and as long as the eyes ; strongly punctured, 

 shining, sparsely covered with long, fuscous hair ; the 

 antennal tubercles shining, smooth, piceous at the apex. 

 Oral region piceous ; mandibles ferruginous, broadly black 

 at the apex. The scape and basal two joints of the 

 flagellum ferruginous ; the flagellum brownish beneath ; 

 the third joint is distinctly longer than the fourth. Thorax 

 about twice the length of the head and of about the same 

 width, scarcely narrowed towards the apex ; above coarsely 

 rugosely punctured ; at the base the sides project into 

 a stout, blunt, triangular tooth, in the middle there is 

 a smaller triangular tooth, and at the top of the median 

 segment on the sides are a few teeth, the lower indistinct. 

 The median segment has a sharp oblique slope, which is 

 for the greater part blackish ; the top serrate, the three 

 middle teeth being much the larger. Except the apex 

 of the metapleurse, which is strongly punctured, the 

 pleurae are shining and impunctate. Abdomen black ; the 

 apex of the first segment with a small, the second with
